No market order without GO

Market (or marketable) orders need an explicit written GO — default is limit/last-look so the agent cannot chase a print into a gap. Pair it with reject agent place without a fresh quote, never skip review before place, size from sleeve not from hope, confirm buying power before place, and write GO before scale-up.

Answer first

Before a live place: default to limit or last-look. Allow a market or marketable ticket only when you wrote an explicit GO for that order — why marketable is allowed, max slippage or kill-if-gap, size from sleeve rules, buying power and a fresh quote checked in the same review step. Chat urgency and a green day are not a GO. The human still runs review before place. Agent Lane publishes the checklist. We do not place trades, hold wallets, invent broker UI, or run your agents.

What this page is

A short operator guide for the order-type GO on the shield — no market order without GO — so the agent cannot chase a print into a gap on a marketable ticket. Pair it with reject agent place without a fresh quote, never skip review before place, size from sleeve not from hope, confirm buying power before place, write GO before scale-up, read-only quote before trade connector, and the shared-box checklist.

We are a publisher, not a trading desk. Product screens change; read order types and quotes on the official page. We do not invent market-order menus or Agentic click-paths. You write the GO and enforce the default at review.

No market order without GO in plain terms

• Default limit / last-look — live places use limit or last-look unless a written GO allows marketable.
• Market / marketable needs GO — any ticket that can take whatever the book gives at submit needs explicit written permission for that ticket.
• Same review step — GO + fresh quote + size from sleeve + buying power before approve.
• Gate at review — enforce at never skip review before place; reject marketable without GO.
• Not a GO — chat urgency, FOMO, “just hit the print,” or a green day alone — see write GO before scale-up for scale GO vs this order-type GO.

Why chasing a print is the failure mode

• Gap fills. A marketable ticket into a thin book or halt/resume gap fills far from the chat number — reject agent place without a fresh quote.
• Size still “fits.” Sleeve size and BP can look fine while the fill wrecks the risk unit — size from sleeve not from hope, one risk unit per idea.
• Urgency skips the card. “Just market it” without GO is standing skip energy on order type — never skip review before place.
• Hope pricing. Chasing the print without limit/last-look is the same hope that skips written scale GO — write GO before scale-up, confirm fills in the broker, not chat.

Where it sits in the shield stack

1. Read-only quote before trade connector — prove prices before place rights.
2. Size from sleeve not from hope — written ticket size rules.
3. Confirm buying power before place — venue cash/BP covers that ticket.
4. Reject agent place without a fresh quote — price freshness in the same review step.
5. No market order without GO — order-type GO; default limit/last-look.
6. Never skip review before place — human gate enforces the check.
7. Write GO before scale-up — separate GO before limits change (not a substitute for order-type GO).

Healthy flow: quote ladder → size from sleeve → read BP → fresh quote/last-look → order type under written GO (default limit) → review → place → confirm fill. Skip the order-type GO and a well-sized thesis still chases a print into a gap.

How to run no market order without GO

1. Default limit or last-look. Sleeve rule on the named plan — name the strategy before connect. No invented UI.
2. Write the market-order GO when needed. Why marketable, max slippage or kill-if-gap, size from sleeve rules, BP and fresh quote in the same step. Large tickets: two-person rule.
3. Same review step as quote, size, and BP. Official venue order ticket and quote/last-look — read-only quote before trade connector.
4. Reject marketable without GO. Switch to limit/last-look, rewrite the GO, or skip. Do not “hope the print is still there.”
5. Place only after human review; confirm afterward. Never skip review; then confirm fills in the broker. First live after novelty: dry run.
6. Journal overrides that chase prints; keep scale GO separate. Journal every override; scale limits: write GO before scale-up; if something misfired: revoke before you debug.

Practical checklist

• Default limit / last-look written on the named plan.
• Market / marketable only with ticket GO — why, max slippage or kill-if-gap.
• Fresh quote + size + BP in the same review step as order type.
• Reject / switch to limit / skip if marketable without GO.
• Review before place still on — human enforces the gate.
• Chat urgency is not a GO.
• Confirm fills afterward in the broker UI.
• Dry run done before first live with a new connector/strategy.
• Overrides journaled if anyone chases a print without GO.
• No invented UI. Official order ticket and your notes; you enforce.
• Shared-box pass. Who can approve a marketable place without a written GO on a shared computer — see shared-box.

FAQ

What does no market order without GO mean?

It means: do not let the agent submit a market or marketable order unless you wrote an explicit GO for that ticket. Default is limit or last-look so the agent cannot chase a print into a gap. Pair with reject agent place without a fresh quote, never skip review before place, size from sleeve not from hope, confirm buying power before place, and write GO before scale-up.

What counts as a market or marketable order?

Any ticket that can take whatever the book gives at submit — market, marketable limit through the bid/ask, or similar venue labels. Agent Lane does not invent order-type menus; read your venue’s official labels. Then review before place.

What belongs in the market-order GO?

Written before approve: why market/marketable is allowed for this ticket, max slippage or kill if the print gaps, size from sleeve rules, and that buying power and a fresh quote were checked in the same review step. A green day or chat urgency is not a GO.

Why is chasing a print the failure mode?

A marketable ticket into a thin book or gap fills far from the chat number. Without a written GO and limit/last-look default, the agent can race a print you never intended — size and BP still look fine while the fill wrecks the sleeve. See reject agent place without a fresh quote.

Does this replace reject without quote or write GO before scale-up?

No. Reject without a fresh quote is the price freshness gate. Confirm buying power is the cash/BP gate. Size from sleeve is the ticket-size rule. Write GO before scale-up is before limits change. This page is the order-type GO. Never skip review is the human ticket gate. You need the stack.

Do I invent a market-order or last-look broker UI?

No. Use the official venue order ticket and last-look/quote screens and your written sleeve rules. Agent Lane does not invent order-type dashboards, last-look menus, or Agentic click-paths.

Where do I apply this next?

At review before place: default limit or last-look; require a written GO before any market or marketable ticket; check fresh quote, size from sleeve, and buying power in the same step; then approve or reject. Confirm fills afterward in the broker. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
